Brian Eno's The Fat Lady of Limbourg for the Raspberry Pi



"Here's an updated version of Eno's favourite chubby girl, but rendered with a slimline synthesis model. All in an attempt to get this runnable on a single Raspberry Pi. This uses the non-oversampled synth, so everything is computed at 44.1kHz. It's using the newer variant of the BPCVO model, and I've redone all the synth presets to remove the filter on everything pitched to eliminate that particular computation burden. And there are tricks you can play to bring back a 'filtery' sound - for example, morphing from sin to saw or sin to square sounds like a filter opening up as harmonics get introduced, and that trick has been exploited to turn the pair of 'Brass' into pure 1980s digital filter-free synthesis. But despite the trick (early ramp via EG to morph from sin to saw, giving a harmonic enrichening over the first 100ms or so of the sound) you simply can't replace a filter with tricks, so the sounds do suffer as a result. But hey, no free lunches here, the goal was to make it burn less CPU and still get a decent sound. So the 'Fat Lady' bass has also gone filterless, ditto the Warm Jets 'guitar', ditto Phil's Wiggly Manzanera. The percussive elements remain filtered as they just have to be, they rely on the resonant filter to generate anything at all apart from hissy noise.

But after the filter removal and the performance tuning, this version now runs in exactly 24% of an iPad 2. It may actually run on a Pi in this form. Really, there is a damn good chance that £20 of woefully underpowered educational computer will be able to synthesize this in real time, without resorting to a Pocket Orchestra. Bear in mind, 'this' is now 14 notes of polyphony, many stereo delays (seven? eight??), a global reverb and 10 separate synths.

Audio was captured from the iPad and not processed in any way, these are exactly the bytes that I computed. Cool, eh? Plus, big bonus, you get the Eerie Noise - which is actually a combination of a dedicated 'Eerie Noise' synth and the pair of brasses, turned way down and pitch bent to buggery. Yay!

Next step - get this codebase rebuilt on a Pi and actually run it."

"Headphones highly recomended
this is all played Live from scratch.

Gear used: Waldorf Blofeld, Arturia Microbrute, Elektron Machinedrum, Akai mpc500 as main sequencer, Korg Ms2000, Clavia Nord Modular G2 and DSI Tetr4. Hardwire DL7 and RV8 were used on the Tetra."

Got Random? - A Serge Modular Synthesizer Tutorial


Published on Jun 18, 2014 Doug Lynner·23 videos

"Use a Serge Smooth and Stepped Function Generator to create a random voltage generator.

Though this is illustrated on a Serge the concepts apply to many modular synthesizers. Let me know how you apply this on your modular synthesizer.

To see the modules used in this patch in detail see the Mystery Serge at http://www.serge.synth.net/gallery/dl....

Korg KR 55 Drum Machine with Midi & seperate output mods

via this auction

via the seller: "This was produced by Korg & was one of the last preset drum machines produced.It had 96 patterns plus fills.The sounds are all analogue & have a TR 808 sort of sound (if you never heard it before).

If you are a Depeche Mode fan then you will certainly have heard this on their early recordings,the snare & Hi Hat sounds being especially prominent.

I bought this unit back in the early 2000's & had it modified by Analogue Solutions to accept midi triggering (also has a Midi thru) & provide separate outputs for the most useful sounds."

Dividing Clocks: Gezeiten Ultima Ratio Eurorack Module


Published on Jun 18, 2014 instantknut·12 videos

"Playing along with my eurorack modular synthesizer and testing the Gezeiten Ultima Ratio clock divider module.
The track is entirely made with the modular with just the inevitable addition of reverb :)

The Ultima Ratio is used to provide 3 clock streams to synchronize the Grids drum sequencer and both Moskwa sequencers with different clock resolutions.

I play with the clock ratios in realtime and also make use of the makro attack/release envelope generator to provide control voltage to modulate the cutoff frequency of a dual Korgasmatron filter.

Make Noise Erbe-Verb Overview Video


Published on Jun 18, 2014 MAKEN0ISE·52 videos

"The Erbe-Verb is more than a collection of reverb algorithms or presets, it is a unique, modeless, continuously variable reverb algorithm with complete voltage control. Typical reverb types such as plate, room, hall, shimmer and others may be programmed by adjusting the knobs. The continuously variable algorithm allows for hybrid and unreal spaces to be found. Traveling between spaces is possible by modulating the algorithm or manually sweeping parameters. More than an end-of-chain effects unit, it's a whole new building block for modular synthesis. Like the Echophon, it's coded by Tom Erbe of soundhack.
